  • ELEMENT FOR MANIPULATING LIGHT
    Publication number: 20200116906
    Abstract: A method of using a non-woven material, preferably a wet-laid non-woven material, as a light-distribution element, includes: providing the non-woven material, the non-woven material including: (a1) 1-50 wt % matrix fibers; (a2) 50-99 wt % of at least partially thermally fused binder fibers; and (b) 20-200 wt % of at least one filler polymer. The proportions by weight of matrix fibers, at least partially thermally fused binder fibers, and at least one filler polymer in each case relate to a total weight of the non-woven material without the at least one filler polymer The matrix fibers include at least one matrix fiber polymer and the at least partially thermally fused binder fibers include at least one binder fiber polymer. The at least one matrix fiber polymer and/or at least one binder fiber polymer independently of one another have a refractive index “n” of 1.3 to 1.7.
